i just picked one up this week, have only put 10 rounds through it for testing (5 buck, 5 slug) and i really like it. i've shot one with a pistol grip before, mine does not have the pistol grip because i shot one with it before lol basically don't get the pistol grip or there goes your accuracy and you better have a good tolerance for pain.
so far no problems with it (then again only 10 rounds) but at the same time i have a mossberg .22 and i've found that they go against the saying "you get what you pay for" thousands of rounds through my .22 and i've had one misfire. no problems with the gun and i'm quite pleased at what mossberg delivers for the money.
some quick advice though, run a search for the 88 and read what people have to say here, i did that before i bought it and it seems only 1 or 2 people had problems with the gun not firing due to a stiff spring or something of the sorts.
