9mm Canik Elite Shooting Sports range SP2022 TP9SA visit

Range Report – Canik TP9SA

I took the TP9SA to the range this weekend.  It shot well!  I’m very impressed.

Some notes:

  1. This is the first striker-fired gun I’ve ever shot.
  2. I shot 108 rounds of Remington UMC 115-grain (megabox).
  3. I was shooting from a distance of 10 yards.
  4. There was one stovepipe that occurred when firing the first magazine.
  5. There was one failure to feed that occurred when firing the second magazine.
  6. The trigger is great!  It feels hyper-sensitive.  Reset is loud and tactile enough for me to know when it resets, without issue.
  7. I shot with the larger of the two backstraps…I honestly can’t tell which of the two fit better in my hand, though
  8. A lot of my shots were to the left of the bulls-eye (my left, when aiming).  At first, I thought the rear sight needed to be drifted, so I used Kentucky windage and aimed maybe 1-1.5″ to the right of the bulls-eye and I hit the bulls-eye.  I decided to stick with using the proper sight picture because I know from my prior range visits that I needed to work on trigger pull and finger placement.  Well, the last magazine was very good…I placed a good bit of my rounds in the bulls-eye while using the same sight picture I’d been using the whole session.
  9. Instead of continuing to become familiar with the TP9SA and work on muscle memory with this gun, I switched guns and shot with the SP2022 the last 20 minutes of the session.  This was a bad idea, as the next 20 minutes, my rounds were all over the place.  Next time, I’m only coming with one gun.

I’ve some video footage of the range session, but only of my SP2022. The video is here:

The target is far enough away to where you can’t see a damned thing…sorry about that.  I’ll work it out on the next visit.  I supposed I could lower the FOV setting on the camera, as well as move the target up a bit (in good/bad guy situations with handguns, 10 yards is a bit excessive as far as self defense goes, IMO).

Another thing I did was to test the 9mm Federal HST JHP I have, just to ensure it didn’t jam…I saved it for the last 5 minutes of the session, as I wanted to shoot them while the gun was dirty.  I shot 10 JHPs without issue.  As well, I was only able to shoot them through the SP2022.  I’ve 10 left…I’ll shoot those through the Canik on my next range visit.   The Canik cleaned up pretty well.  There’s quite a bit of barrel wear at the ejection port, though…just the paint coating, though.  It’s not a huge deal, although my SP2022 has more rounds through it and has NO outside barrel wear.  I did lube the Canik VERY well before the range session (with TW25B)…the rails looked good.  There was a tiny bit of wear on the underside of the slide itself, though, and I’ve no idea what caused it, but I’ll be sure to apply some grease to that area before the next visit.

The feed ramp already has what looks to be copper on it, where the bullets contact it while being fed into the ramp.  I’ll leave the ramp alone, though…as long as the gun functions properly, I’m happy.

I’m looking forward to the next range visit with this gun!

.40 limp-wrist loose hold P250 polymer

Loose Holding AKA ‘Limp-Wristing’

There’s a guy on the forums that I frequent that’s been having very chronic feeding issues with his Sig Sauer P250 .40 cal.  He arranged for Sig to take a look at it and fix the issue, but Sig returned the gun, stating there was nothing wrong with it and that they weren’t able to duplicate the issue.  He complained when it continued to have feed failures, so they suggested he replace the recoil spring.  The gun owner was almost livid because he thought they should’ve done that when they had it (but remember, they couldn’t reproduce the issue).  So, he replaced the recoil spring and shot 200 rounds through the gun with the new spring…the feed issues went away, but now he’s having an issue where the slide stays partially open after ejecting the round (he has to manually cycle the firearm).

Both the feed symptoms that he initially experienced and the resulting issue of the slide partially cycling after brass is ejected are chronic signs of loose holding or what’s called ‘limp wristing’.  Limp wristing can be caused by a loose hold or insufficient strength when holding the firearm while shooting.  Polymer guns are more prone to limp wristing than all-metal guns, since polymer can flex.

The gun owner swore that it wasn’t limp-wristing when he was having the initial feed issue and stated that he’s shot other .40 cal handguns without issue.  He specifically mentioned a .40 Beretta M9, which is an all-steel gun, which would probably not have such issues.  After he swapped in the new recoil spring, he then had the partial cycling issue, which is yet another symptom of limp-wristing.

The fix for this is usually to firm up your hold on the weapon, if possible, change to heavier grain ammo, or to get a different handgun.  The P250 is a convertible gun.  I believe a .357 P250 can be converted to .40 and vice versa…I’m not sure of 9mm.  I think 9mms can’t be converted because there’s not enough room under the slide to accomodate the larger barrels…you’d have to get the slides for the .40/.357 for that to work.  The gun owner might be able to convert it to 9mm but I doubt he’ll be willing to spend more money on a gun he currently can’t shoot without cycling issues.
