Blume. You bought that off me I'm sure. I know we had a discussion regarding the mags cycling. Think this was the post..... http://www.rugerforum.com/phpBB3/viewtopic.php?f=2&t=196081&hilit=P89
Sounds like you got that figured out and I hope the old oem mags work as well, but if I recall it only came with 2 mags. The Meccgars cycled ok from what I recall, but I never fired that gun. That was part of a package deal I got and already had the P89 safety.
Roy ... I still have yet to fire some of those other P series...LOL. It has been riding season and I have not even checked in here since...well, it's been awhile. Last time at the range and it was with the Charger and some revolvers....
