I have the LPA MIM on my 1322 with steel breech and wanted one for my 1377 but couldn't find one in stock.

I found this 3D-printed item and installed it - works great and practically cost nothing!

If you don't have your own 3D printer, then it might be better for you to find someone local to make one for you.

So you have a breech without a sight dovetail?

GMAC custom mills the back of the breech flat for use of the OEM 13xx/22xx rear sight, on some of their breeches. I got one that doesn't.

Personally rather then filing, I'd just get one for 3/8"-11mm groove the breech has.

Almost like my Gmac custom one.

Without a jig, filing a rear sight notch squared, will be hard.

There is this option..

Maybe I jumped the gun on the question milling the slot. I have no Idea. I've seen those ones before. Not sure on those

I would need it done right.

If I was going to do it, I would get it milled flat on the backside for using the OEM sight.

I have the same dilemma.. I got a LH GMAC breech on my 2289, and I want to run irons. Like a fool, I opted for no notch, or milled.

Guess I'll run a reddot, since a scope obstructs the loading.

I got zero sights on mine ATM.. Need a brake/front sight. Someone cut the barrel down to 12" and didn't file the flat for the OEM front sight. Then figure a rear sight..

They been on the back burner since getting my HW 45

Sounds like a good opportunity for a member with a 3D printer. I bet they would sell quite a few here.

Yes I did..

I found this in my tool box. With a low profile adapter, it should work. I might just need to get a taller front sight pin for my muzzle brake.
