I bought one when they first came out, true to it's little brother the 92, it has never jammed. It is very accurate and very comfortable to shoot, my wife loves to shoot it as well. Never considered SBR because it is compact to begin with.
No reason to sbr. I suggest the 92 version that accepts the same mags as the 92 pistol. It's light weight, comfortable and accurate. Does not suppress that well and I hate the safety. Overall I like the gun, even with is few drawbacks. For the price it's hard to beat
It's super compact and lots of fun. I guess it depends on what you want from it, though. It would be cool with like 2-3" less barrel, but it hardly seems worth the effort. If you plan to customize it a lot, maybe something else would be more suitable.
