There's not a lot that's not already been said but I'll add my perspective as a PS90 SBR owner. If you're worried about ballistics, understand that was never a goal of this firearm. It isn't a magnum elk slayer or anything, but if you think of it as an alternative to a pistol caliber carbine you're on the right track. Having said that, it can be a nasty little round especially out of SBRs and rifles. There are a few pics floating around of 197 being used to take a whitetail that absolutely devastated its chest cavity.

Also, it was really meant to be enjoyed in SBR form. If you're going to keep it 26" I'd just as soon go with any rifle caliber bullpup, you'd only be adding a pound or two, and have far more effective ballistics. In its SBR form it is about as short as you'd want to go at <20", and is barely more cumbersome than a pistol while being significantly easier to shoot quickly/accurately.

I do feel comfortable using mine as an HD gun, due to its size/ammo capacity. My main HD gun is still my Mk18, though. You may also find its a handy little coyote gun, or useful for similar sized pest control. The 197 does use a 40gr v-max bullet after all, and I have found mine is actually very easy to shoot for tight groups, at least considering what kind of gun it is.

I keep hearing the ergos are amazing. Are they really? It's hard to believe looking at it but enough people say it.

Are there different versions? I just want one with a tail so that I can put an Aimpoint or RMR on it.

With the 40g federal ammo easy enough to find at around 35 cents a round I think I can justify shooting it.

Looking at getting one but am a little apprehensive about it. I would like to hear your thoughts from any owners on here. I have a few AR's and a 762 rifle but was looking at something that was small and better than a 9mm. I really like that the whole weapon measures 26" long and has the capability of having 50 rnds on board. I guess I am skeptical about the actual ballistics of the 5.7 round and its availability as well. Would like to hear what fellows owners have to say about that and the overall functionality of the weapon.. Thanks S...
