I recently held and really liked the Walther PPS, but with all the reports of regular and +P ammo causing a spring to come undone and lock the slide back I'm wary of buying one for a single-stack/summer carry gun. So this brings me back to the HK P7 PSP, which I've always been tempted to buy. There's one for sale with 2 mags and a Crossbreed Supertuck holster for $600 plus shipping. Seems to be one of the Grade B's with slide wear. Is this a fair price? Anything I should look for in buying a used P7? I'm also not really convinced that I NEED anything right now. I'm considering buying a Saiga 7.62 and a conversion kit, then flipping it on Gunbroker to make the P7 PSP a little cheaper. Help me spend this money that's burning a hole in my pocket WMD! Is there any reason you WOULDN'T buy a P7?
