I own two r51’s. I like them a lot. Newest edition smoke grey frame. I shoot my guns fine and i find 147 ‘s seem to work well. I carry federal 147 hst’s in my smoke gun. I see some think its ugly . I think its ppk-esk myself. I like the pistol and it is well built and better machined than more expensive plastic guns on the market. If I were you look at the smoke grey framed one before you buy the black one. I own a lot of guns this gun is well built. My guns function fine.
