I am only really familiar with USPSA. Right out of the box, the SFX is legal for Production Division. That means it is legal for Carry Optics if you put your red dot on it. You can also shoot Limited with it if you want to load your mags full.
Yup. Under actual range conditions I was fine with the red dot and didn't notice any "spidering". I have no complaints with the Vortex. So far, I love it. It does take a pit of practice to get used to but I am good with it now. There is no doubt, it is much faster than aligning iron sights. If it holds up as it should and performs as it does now.....yeah baby.
I feel like it is a good training aid too because in order to get the dot to show up you have to hold the gun in a good position. The accuracy of my shooting goes up because you can see the dot move as you shoot (I can do this with my iron sights but only sometimes - "calling the shot" is easier with the dot), plus there is no guess work about how centered the front sight is in the rear sight or guessing how close to perfectly level it is with the rear sight. So your misses are because of trigger or grip only, not simply a minor misalignment of the sights.
I was worried about fast followup shots and losing the dot (for USPSA) because at first it completely disappears after a shot and takes a second for you to re-aquire. But in just a few minutes of practice, I was able to keep the dot visible through the entire recoil stroke and could get .24 second splits on two shot groups. Not as fast as my splits with irons but more accurate. In order to have the dot stay visible I had to improve/correct my grip so that is already a benefit.
I think the crimp is good. used the Lee FCD and worked it down so I have the slightest mark on the bullet. The cartridge set at 1.115 when chambered with the barrel out of the gun is proud of the end of the block. If chambered from the magazine when the slide is racked by hand it sticks as the extracter tries to pull the round out. If force is used to rack the slide the bullet is stuck in the rifling or the throat and is pulled from the brass. Happens with Berry 124 THP, Missouri Bullet 115 grn parabellum, and Ozark 115 RN. All of these have to be set at a COL of 1.090ish to work. 1.110 is too long. Have a cartridge gauge too and all fit fin in it just not the gun. I measure .775 from the step to the top of the block opposite of the feed ramp.
Is it possible that you have so little crimp that the bullet is being thrown forward out of the case and into the rifling with the force of chambering?? There is no way with this the length you have that it should be hitting rifling.
Another thought. Measure some factory rounds OAL and find some that are greater than 1.110 and see if they jam in the rifling.

I wondered if the last owner used the wrong type of cloth to clean the glass. It really irritates me--mine has spidery red tentacles that are really obvious when casually 'handling' the gun. When I was shooting I tried to ignore them.
It was very noticeable when hand holding the sight, but under range conditions it was a crisp dot for me. Or I perceived it as a crisp dot. One way to check if it is the glass or your eyes is to turn it on, look at the dot (and spider blob) and rotate the gun (like along the axis of the barrel). If the spidery marks rotate with the sight as it rotates the defect is in the sight, if the orientation of the spider blob stays the same, it is your eyes.

What is the longest COL you have used? I loaded some Missouri Bullets 9mm parabellum at 1.115 and found that when they chambered and the slide was racked and the cartridge ejected the bullet stuck in the rifling and powder was spilled. Have to have a COL of 1.085 so this doesn’t happen. Oregon trail 115 LRN suggested COL is 1.100. That is too long also and 1.085 works for them too. Is the TP9SFX short in the chamber?
I don't think so. I wonder if something else is going on there. I've run 1.145" with no problems in my SFX.
I just got back from the range. WOW! Shooting steel plates with that Vortex mounted on my TP9SFX is almost like cheating. I was smoking those plates.
I just tried mine out. Same thing. Holy crap! After getting used to it for 5 minutes, I was clearing a 6 plate rack from 13 yards in under 9 seconds (including draw) with no sweat. Did it once in under 7 seconds! This is within my first 30 minutes of ever using a dot sight on a hand gun. Dang. Also my spidery blob effect was completely gone when the sight was in actual use.
I just got back from the range. WOW! Shooting steel plates with that Vortex mounted on my TP9SFX is almost like cheating. I was smoking those plates. In retrospect, I should have purposely missed some because I asked my range buddy to shoot for $5. per plate and he said no way. He is also my age (70) but has crappy trigger control and tends to anticipate recoil and yank his muzzle down. I mounted a Vortex on his S&W high falootin CORE M&P and he still misses half the plates. That S&W pro shop gun has a really crappy trigger. For what he paid, he took a spanking. All my Caniks have much better triggers right out of the box. I told him to write to S&W and complain. Although from my past experience with S&W, I doubt if they will do much. They will most likely offer to do a trigger job and charge my buddy full tilt. If so, he will go ballistic. I told him six months ago to buy a Canik but nooooooooooo.....he had to have the S&W pro model. Oh, and another thing. His "pro" gun is ported and after he shot 6-rounds the front iron sight would be blacked out. My factory ported Canik has the porting at an angle so I don't have those issues. God forgive me because I tease the crap out of him for not listening to me.
In fairness to him, yours isn't actually ported unless you had it done, the cuts in the slide are just in the slide not the barrel.
I just got a Venom but haven't mounted it yet. Looking forward to trying it but I'm already noticing serious star burst effect from my eyes (the sight itself is fine, but my eyes see the dot as a spidery blob.
Great video. Does the recoil feel any different with the Sprinco or Glock 17 RSA versus the OEM?
I will add to your data that I am shooting with the OEM RSA and the 28N Red Firing Pin Spring and that works at greater than 98% with my 125 PF loads (147 gr bullet with avg velocity 868 fps). I've had 3 FTEs in about 450 rounds. My OEM RSA must be magic though because I've only ever had those 3 issues in the entire time I've owned the gun, probably 4000 rounds or so.
It's USPSA style shooting. Depending on where you live there should be matches near you. Just show up and shoot. You'll need a gunbelt, holster and a couple mag pouches to begin but other than that the SFX is ready to compete out of the box.
I don't have mine yet but in research I have done, you should use the screws that came with the gun to mount the sight to Plate #1, not the screws that came from Vortex
+1. That's how mine mounted. Piece o' cake.
Going along with this conversation: I assume if I swap back and forth, the iron sights retain a good zero. Is that true? I'm not ready to start competing with the dot yet but would like to practice. But if removing the irons and then putting them back on hoses up the zero, I'll rethink how I do it. And by the same token, does the dot keep the same zero as you take it on and off?

Don't apologize for the hijack...apologize for rubbing "high 60's" weather in my face.
-13 temp this morning with -31 windchill...it is "not-freaking-funny" cold out. I'm thinking of shooting 100 rounds fast feed, just so I can hug the barrel for warmth. Glad I bought two 30 round mags...they should help.
I probably shouldn't tell you the revised forecast says 70 degrees...
Welcome. If you are any where near Galveston, they have a USPSA match at Galveston Rifle and Pistol range next Sunday 1/7. You can sign up on PractiScore. Great group of guys to shoot with and always a challenging match with a diverse group of skill level shooters.
[Sorry for the hijack]
I am thinking of shooting that match. I've never been to that range, have done all my matches at PSC and Area 59. Will you be there for the 1/7 match? Weather looks like it will be high 60's that day.
When you say grip modification... is that stippling and whatnot? I am looking to make my grip larger/fatter. I have put the Hogue universal grip sleeve on it but would like it to be substantially wider. Any possibility there is a solution for that problem?
I've been loading X-Treme 147gr RN plated bullets with 3.1gr of Titegroup and OAL of 1.13x", CCI primers. All make just over 125 power factor. I'm not sure if accuracy is all that awesome but I haven't noticed it being crazy bad either.
So have you not shot the match yet. My advice for Steel Challenge when you are new to it (as I am): take your time and be ready to be humbled. You will almost certainly shoot faster than you are capable of when you start. If you are new to match shooting, hearing the timer BEEP will make you shoot frantically at first. Also, you sit there for the whole match listening to the cadence of the other (more experienced) shooters and it is human nature to sort of try to match that cadence. Then you will have 1, 2, 5, 10 misses - sometimes at a single plate. It can be very humbling and even embarrassing when you start out.
I have gotten started in USPSA with my SFX and it has been a great experience. Out of the box with no mods, I have about 5000 rounds through mine. Never had a FTE, a stovepipe, a FTF, nothing. I did break a firing pin but I take the blame for that because I stupidly dry fired with a laser boresighter in the chamber. Other than that, it has been 100% through 5 or 6 matches and dozens of practice sessions with the cheapest factory ammo I can find and my own reloads which are a hair's width above minimum power factor. I have the original RSA as well. I did put the Glock lighter striker spring in when I replaced the firing pin.
