hwagan Posted March 16, 2010 Report Share Posted March 16, 2010 I've had the same problem with my USP not getting quite far back enough to pick up a round - Quite a rare problem and not a huge issue, especially considering overall performance in the cold is excellent. I might pick up another recoil spring and play with cutting a few of the coils off - Good thinking! Link to post Share on other sites
reaper16 Posted March 17, 2010 Author Report Share Posted March 17, 2010 Well, im putting in my order for a KWA USP tonight.... I guess I'll through in a plastic propane adapter(15 vs 24...i think i can manage) too since green gas is hard to reliably find round here...unless they will work on 134a...which i doubt.

tome Posted March 17, 2010 Report Share Posted March 17, 2010 Yeah mine struggles on 134a. It will barely cycle. Maybe this will change in the summer though when the temperatures hit 20+ celcius Link to post Share on other sites
greg Posted March 17, 2010 Report Share Posted March 17, 2010 in the summer though when the temperatures hit 20+ celcius Do you think that will happen this year? Greg. Link to post Share on other sites
Ecthelion Posted March 17, 2010 Report Share Posted March 17, 2010 Oh, I missed this one by just a hair since it seems the original poster has already made his decision.\ I have extensive experience with both the System 7 USP, the KSC Glock series and the TM 5-7, M1911, and Hi-Capa. I've owned and shot them all extensively. It all depends on what you want. System 4 USP Pro: Nice metal slide and frame is very well made, much better than Marui exteriors slide is extremely well fitted to the frame, no wobble whatsoever, better than older Marui pistols, but comparable to the 5-7 bbs are easier to load hopup is slightly easier to adjust than any Marui pistol Con: significantly less accurate than any TM pistol because of the hopup System 7 does give it nice consistency, but not better than a Marui. Also the mags tend to leak more. Racking the slide will NOT remove a chambered BB, Marui guns will. Recoil is significantly stronger than TM M1911 or Hi-Capas, but weaker than 5-7 (the 5-7 has exceptionally strong recoil) Link to post Share on other sites
