The promag have the potential to lock the bolt back. I dont know about the RRA block, but my hahn dedicated block locks back both colt and promag no problemo.
ETA: What kind of mag is RRA going to use now. A whole new mag, or a newly modified one? |

RRA was talking about an entirely new RRA magazine.
That's where I'm not understanding. The RRA people say that the bolt will lock back with their block and a Colt mag but they have no idea what a promag is. The concensus here seems to be that the hahn people have bad results with Promags and the RRA people have good results. The hahn block needs removal of the bolt catch to install the RRA unit does not- so it would seem to suggest get RRA as they supposedly lock a std Ar15 bolt catch; drop in; and function with Promags. Can anyone confirm that [bolded statement] is true? |

We're working on new metal 32rd mags from dedicated dies that would allow us to keep dimensions exact. I've personally not experienced problems with the modified Uzi's, but we've received feedback that some, but not all, users have some problems with some mags in some rifles/conversions. As long as we're looking at doing it, we're also goign to include a bolt hold open feature into the new mag. Should have some prototypes in hand in a few weeks. If acceptable, production would follow shortly thereafter.

This is my second build...both have wanted to slide up or down...usually up and then is rubs the carrier slowing it down and causing failures. I know this one moved for the first time when my buddy slapped the mag in.....and I had the screws tight and also had a second set screw butted up agains the first one with blue locktite (blue is the wimpy stuff). I just pinned it (if you want to call it pinning??) so I know it will NEVER move again....hate to have it fail in a mad bowling pin or pop can frenzie

ProMags hold the bolt open each and every time on my RRA factory 9mm.

I think the choice is obvious.
Get the RRA block, and promags. Thanks. I'm excited at the prospect of affordable 9mm mags that will lock the bolt back. I think I'll drill and tap my block and just use an allen cap screw through the lower to fix the block in place when I want to use the 9mm. It sounds like that's the only major issue with the RRA (people mentioning sliding around as if it's going to fall out.) |

I wish someone would start making new 20rd 9mm mags. I just like the smaller/shorter size of a 20rounder.

I wonder when the promag 20's will come out for sell? I will buy several of them. The 32rd promag I have just works perfect. I never used it at first as I had about a half dozen colts and gave it a chance one day while out shooting and its been flawless eversince.

my promags hold the bolt open with my RRA, they are also easier to load than colt mags, but i want 20rd mags!

Steve,
Just following up on this. This is some of the best news I have seen in a loing time regarding Pistol Caliber RRA products. Do you have even a guess as to what one of the RRA mags would cost? I am so tired of trying to make adaptations work. You read these boards and about half the posts are about block / mags not working (heck half the posts in this thread talk about this) I think RRA would really be onto something to answer the "whole package" question. I know I would be in line for 2 of the new 9MM pistols myself. Thanks

C Products is about to start producing 9mm AR-type mags for Colt/RRA/CMMG 9mm carbines. As far as bolt hold open, I'm not sure. But another good mag out there, esecially one that doesn't cost and arm and a leg, will be nice.
