i recently traded for a B prefix Covina stamped AMT Hardballer. the pistol is very tight and machined well, no gotchas, shoots well and really wants to group. i ran AE FMJ and some old heavy hollow points thru it. it devoured them all. but...always a but isn't there...it failed to feed the last round in 3 different magazines. i did not get factory mags as they went missing long before the fellow i got it from. i'm suspecting the magazines cause the FTF the last round and will order a Wilson Combat mag to verify. also it has the factory skeletonized stainless steel grips, while they look good, i don't find them to be very practical, so i'll be looking for some replacement grips, they need to be full length, and really don't like the one piece finger grip type. nice wood or quality aged fake ivory would be my preference. any info, other than ebay, would be appreciated.
