The HK USP is extremely strong and makes an excellent 45 Super
anyone set up a gen4 g41 as a 45 super? With captured springs in a proprietary assembly I wonder if its possible to shoot the super in the gen4 21 or Gen4 41? I saw a used gen 4 41 today for $525, a very good price. HOwever I believe the 41 might not be suitable for the 45 super, lighter slide.
Yessir a bud did, he's talked to me about doing my gen 4 21 a couple of times, iirc he bought a StormLake, KKM? barrel, new steel guide rod with bushing and recoil spring, I think he also said something about a new stronger firing pin spring, said he's into the conversion well under 250 bucks, he shoots 255gr hardcasts, don't remember the speeds he loads to.
