New 738--if you put a full mag(6 rnds) into pistol & then try to pull the slide to the rear to "rack" a round into the chamber--it is "impossible" to pull the slide to the rear. It's very hard to even get the mag to lock into the pistol---must "slap" the mags bottom to get it to lock in place. You can insert the mag easier if the slide is in the open position & then hit the slide release to chamber a round; but then you only have 5 rounds in the mag--if you then drop the mag & put a sixth round in --the problem starts all over again. It was advertised a a 6 + 1 pistol--but I guess I can only use it as a 5 + 1. Anyone else have this problem & was there a solution found, short of sending it back to Taurus ???????????????
