Pistol recoil spring spacers/washers

[takatorikku]

Does anyone use these for their stock recoil springs? I just happened to find a pair of aluminum washers that were the exact diameter of my spring stoppers (or whatever you call the things that prevent your spring from shooting out) and with a pair of needle nose pliers and barely any work at all, I compressed my large spring in my KSC USP .45 by 3mm.

After a bit of test fires, I find that the slide cycles a lot harder than it used to, and my trusty USP no longer suffers from the "sluggish slide return" if you aim it upwards. In fact, it kicks quite a bit more too, I found that the blowback action was MUCH more crisp and I can barely see the slide move anymore!

Also, since the slide racks much more forcefully now, I get a sort of "ka-chink" noise even though it's plastic. Not bad IMO.

I still have about 5 more washers, I may add another one or two down the road until I get an actual upgrade spring kit for the gun.

Hope this was helpful in any way, and if this was a GBB no-no, for the love of god, tell me soon lol.

Not really a no-no. You're just compressing the spring a bit, which amount to basically putting in an upgraded (stiffer) spring.

The downside you experience is your slide won't lock back after the last shot if your gas pressure is too low, or in cold weather... simply because there wont be enough power to move the slide all the way back.

Also be careful about adding too many spacers, it may lead to misfeeds (specially during rapid firing, which causes more cooldown). Way too many may completely muck up the gun's operation if there's so many spacers the spring becomes completely compressed because the full motion of the cycle.

thanks for the info! I removed one spacer so that there's 2 in, with a 2mm increase, and it works fine even with low gas.
