You would thin those holes would jet gas back towards the shooter pulling the gun forward, but you say it hits harder in the hand now? Link to comment Share on other sites More sharing options...
arkadi Posted October 27, 2016 Share Posted October 27, 2016 Hard to tell what the ports do exactly, without proper fluid dynamics simulation or high-FPS camera capture, no? Link to comment Share on other sites More sharing options...
adamge Posted October 28, 2016 Share Posted October 28, 2016 Greg, are you selling those? Can you make one with the pedal positioned farther forward, like say in front of the front screw hole (I have long thumbs)? Link to comment Share on other sites More sharing options...

Yes, you're right. The only way to know weather or not improvements in lessoning muzzle jump or perceived recoil is to get the shooter out of the evaluation. What is really needed are force transducers in X-Y-Z mounted on a pistol before making any changes to the comp. Take the G force measurements and then repeat the exercise after making compensator changes. We would have interest in the X-Y data, not so much the Z, although there is rotational force being delivered to the pistol due to the bullet having imparted spin. Video of muzzle rise is not so helpful if a pistol is hand held, because as we all have noted, that is a warm fuzzy type feeling as to what the gun shoots like, regardless of the video evaluation method. kneeling... Yes, I can not definitely feel the slide hitting the frame, a sensation I didn't feel at all before modifying the comp. As I'm getting less muzzle rise(As witnessed in the C-More.) the thing that I'll probably try next is safely getting rid of as much slide mass as possible to lessen the momentum of the slide -- some time this winter -- In particular behind the breach face for now. And, yes, it seems as though the gases are being redirected to the rear but I, the shooter, don't feel any air movement on my face or hands -- but the RO's do! Having made the comp mods, subjectively, I'm not real sure the pistol performs any better than before the mods! Except for a minimal decrease in muzzle flip.

TobyJ Posted August 5, 2017 Share Posted August 5, 2017 So what about one of these as an open gun...it's the semi-famous 'SP-01' Compact, or 'Steel compact with a rail'. It's built like a tank, and weighs in at 38 ounces with empty mag. Apparently they are some sort of CZ contract overrun. I'm working on trying to get it approved for Carry Optics under the 'at least 500 offered for sale' clause, as this version isn't listed as a production gun. While I expect it to be approved to run CO, I was thinking about where else I could run it. CZ Custom has a threaded barrel for it that measures 4.22" from the breech face, which puts it right in line with some of the short barreled open guns. It will take regular CZ75 mags, so that part is easy, and with the shorter grip, clearance for a magwell won't be an issue (provided a mag well is available). Optic could go on the slide, obviously, but I would think a frame mount would work well, also Do a SAO trigger, and I think it might work well. One concern I have would be the 9 major loads, but like I said, this thing is built like a tank. Like I said, my plan is to use in in CO, but I like options :-) TobyJ Link to comment Share on other sites More sharing options...
kneelingatlas Posted August 5, 2017 Author Share Posted August 5, 2017 The P01 slide needs a one lug barrel like this So if you want to use a longer barrel like the one from the SP01 You have to grind the front lug off, I did this one with a Tanfoglio compact. It only lasted about 100 rounds of 9 major before the lone lug started to round off. It's possible the CZ barrel would hold up better, but I wouldn't expect it to make it more than a few thousand rounds before wearing out. Link to comment Share on other sites More sharing options...

Not sure, it's my friends. But he got it dirt cheap cause the bullets hit the comp. Was fixed with a dremel If you look closely around half way through, the magwell falls off Link to comment Share on other sites More sharing options...

How many open guns you got? Condolences my brother, as a California resident it's not often I'm complimented on the size of my cage How many Open guns??? That's a tough question What constitutes an Open gun? If it's a gun complete, finished and ready to shoot in competition with belt, holster, mag pouches and mags, I have one! If it's a frame and a plan, I have somewhere between one and two dozen Link to comment Share on other sites More sharing options...
