my RAP 401 feeds anything and everything just fine. it is my primary carry. i carry S&B JHP 115gr.
IMO, it is absolutely reliable. it has never had a single failure of any kind. then again, i only shoot jacketed ammo, no matter how cheap or crappy it is.
Accessories, such as holsters, are hard to come by. Use uncle mike's or make your own holster (that's what i did).
this one, at least, has proven its worth to be a carry gun.
i don't make it out to be the end-all best gun ever, but I'm a huge fan of a gun that fits me well, is reliable, is concealable, and is affordable for blokes like me who don't have trust funds. (got mine for just over $200). given the quality, i would have been willing to pay much more, if i had the money to do so. but i didn't. and i still don't.
fits me well being a big key, too. i have slightly small to average hands. I like single stacks, and i can squeeze all three fingers onto that grip, unlike alot of people. i like the balance. i like the weight.
