Just received my V2 damper system! WOOHOO! As soon as I installed the supplied spring I knew THAT was going to be too heavy what with my gun already having the FBFPS, so I borrowed the recoil spring from my 1911 .22 TCM - 11 pounds. My installation took two shims to get the required "5/100th of an inch" which is like 1.26mm - not much. Removing the Tougher Buffer guide rod with 22/44 dual rate spring reduced the gun's weight, and now the slide can be racked with two fingers! Total installed gun weight 38.8 ounces with comp! This is a gun that's already demonstrated high reliability firing over 700 rounds of full-power 460 Rowland using the TB system. My 37 ounce S&W M69 kicks like a 6-legged mule and delivers less total velocity and energy, and only 5-shots versus 8 to 10 from the 1911!
Did I just see a full-power .460R fired with 9 pound spring and the gun isn't damaged? Does this mean I can replace my tougher-buffer with dual-rate 20/40# spring with the V2 recoil damper and 16# spring? Or even lighter? Talk about enhanced reliability but also having a gun that delivers 1,000 pounds of energy without massive springs is a major plus! Having asked that question, does this mean I don't need a flat-bottom firing pin retainer to add force against the slide in addition to 20-24# recoil springs?
I converted two Glock Mod 21's(with consecutive serial numbers). Absolutely love them. Never had any malfunctions at all. My advice, don't buy cheap 45acp ammo. Talk of the range every time I go.
How do you know how many shims to use? I used all but one; there's no less amount of travel when you rack the slide back? I even put a wilson (blue) buffer on the guide rod and there is the same amount of travel
First take out the Wilson buffer and throw it as far away as you can! Urethane shok buffs shorten slide travel - reducing dwell time, and help "accelerate" the slide forward to further induce feed stoppages. They aren't needed, they're a gimmick, and the people who designed your .460R conversion PROBABLY knew what they were doing without the usual aftermarket over-kill that in almost every case makes a semiauto less reliable. The shims have nothing to do with total slide travel. The shims are used to establish a 1.27mm "compression" between the cylinder end of the guide and piston end. With no shims the two parts are separated by the the little calibration spring. You follow the video exactly - piston against recoil plunger inserted in behind the barrel bushing, and cylinder pressed against the inside portion of the dust cover. You can compress the plunger down against spring pressure. Add shims until the plunger only moves 1.27mm and you have correctly "calibrated" the system. You then install the 16 pound spring and put it all together ending up with a .460 Rowland that gets away with a standard ACP power spring! The air compression system is far more powerful than a jouncy shok-buff and will bring the slide to a halt smoothly, without reducing slide stroke. Feed problems in .460R conversions are induced by the rounds in the magazine not having enough time to lift the stack before the slide comes forward - which is WHY you don't add things that shorten slide travel and dwell time. Another thing that reduces dwell time are the extra power recoil springs that the V2 system can eliminate.

That's what we like to hear, happy shooting!

The spring guide rod is a telescoping air piston that cushions the slide so that it doesn't slam the back of the frame.
I'm gonna have to get one
lol at do no freakout when it jams. should we just start off with 9lbs for the test then?
Does the V2 work commander sized guns?

So 45acp can be ran in a 460 Rowland
Yes Sir!
