Follow up post. Sent my gmr 15 to JP, turn around was excellent. Received it back in two weeks. All mags drop free now. They milled out both sides of the mag well slightly.

Flatland Shooter, when I measured the new 33rd mags they are a few thousandths wider than the gen 5 17's. Front to back the magazines I measured were all about the same. They didn't say specifically what they do. The work order just says cut mag well for swollen mags. I'm guessing they widen it slightly.

Thanks for the comments. I spoke with JP since August they’ve been opening up the magwells in all new lowers to deal with this issue. I’m going to send mine to them to have it recut.

Thanks Boss

No magwell, just a stock gmr 15 tactical.

Hello, I'm having a problem with Glock 33 round mags dropping free from GMR 15. Magazines are new, GMR15 is new. 17 round gen 5 Glock mags drop free. The 33 rounder is tight going in the mag well. Dimensionally the 33 is a little wider than the 17. Don’t remember the exact measurements but it was a few hundredths. I don’t have any extension on the 33 yet but really don’t think the extra weight will make a difference. I have thought about some light sanding on the mag. Or opening up the mag well but really don’t like the idea of filing on a new JP. Is this a common problem with the gmr 15 or the 33 round glock mag? Thanks for the help.

Thanks I appreciate the input. Looks like a combination is probably best route to go. A big stick TF for steel heavy stages/matches. A couple +6's for regular stages. Anyone have any experience with the MBX mini's? Mega seems like overkill.

Old3GNR did you have to do anything to the TF to get them to run or were they good out of the box?

I'm purchasing a gmr15 and trying to figure out which mag extensions are reliable on the 31 rnd glock mags. Taran, TF, ? Has anyone had issues with them running reliably?

Thanks I figured it would be, but haven't found anything that states it specifically from sti.

Does the Hawk have a ramped barrel?

Sure took third c at Indy pro/single stack championship with it first match out early this year. Very fun to shoot, flat too. 180 SNS cast coated, 3.2 titegroup, 1.135 oal

Yeah Gump, just take your dremel with a small sanding wheel or coned one preferably and grid on the hook a little till it fits. I removed a little then tested it about 3 times before I had taken it down enough.

I wouldn't be worried. Henning will take care of ya. Bought his guide rod and they mistakenly sent the wrong one. Called him on it and he sent the right one right away and threw in a free base pad to try out.

Must have took it down, even still the price of these things is getting crazy. Accu-shadows are like 1700

I think you would have to use a 6 inch slide for it to be legal.

Where'd you get the trigger from Gump?

Onagoth if they say they can get them let us know

Interesting reading the rest of the posts. I never had any problems with the block dropping. Ya sorry Nealio I should have clarified I've never used the race master on a tanfo just a bladetech.

Ya Nealio, I like it a lot, though I only used it for my sti edge, which it fits very well. Started with the hogue magnetic holster, used it for a year or two well enough until I ran into a stage at Indy sectional that had you leaning forward to start and my gun kept wanting to slide out. Didn't like locking it because when I unlocked it on the timer the mechanism always pushed the mag button.

That's what I thought too, the k40 is the new large frame 40 mag.

DAA Racemaster for limited and I like the bladetechs for production. Gump, Is the Boss hanger better than the factory doh on the bladetech?

What's the part number for the one piece sear? Do you get it from eaa or grauffel or ?...

What's the pull like on the J&L?

Anyone want to buy a used stock 2 in 40. I wanna buy one with those new grips.
