Rost Martin RM1C magazine disconnector(MD) details

I believe the trigger upgrade is the same, but you can confirm with Rost Martin. Their phone support is excellent, but their email support is not very responsive. Oh, and make sure to use the 15% discount code before placing your order.

Guess I don't need a code. They won't ship even the smallest accessory to Kalifornia!

And I was about to order a compensated rm1c, that bites.

been interested in these pistols for a long while now.

The comped version- not on ca roster msrps for only $20 more than the non comped version but the comped slide and barrel kit from Rost msrps for only $100 less than a complete pistol. I have talked with them about a slide swap post purchase but they just keep telling me that the comped version will be available in ca soon.

EDIT- just checked the roster- looks like the CA COMP is now listed.

I bought my RM1C comp’d from Turners. It was cheaper than the non-comp’d.

FFLs can get everything on the roster. They won't ship a mag spacer or the trigger to an individual in this state.

Got it, but it’s the principle of the matter. I’m still buying one.

I see. Damn, Welded? I though it was some pin or spring. You happen to have after images. I do have tools, but can't find any information about the location for the magazine disconnect. Until I came here and search and search and you were the first with some form of image.
I can see it now, but trying to figure out how to take it off.
I may have to do some digging. But a photo will help and what angle to go in. Lol.
Appreciate it.

If you take a pair of needle nose pliers and give it a little “bend” from the open end, it will bend back about 1/4” and then snap right off.

I was thinking that I would have to use a cutting wheel and grind off the rest. You did this already? Pictures?

Confirmed this works. It broke off right at the part that's welded to the trigger bar. Left a little sharp bit that was easily filed off. I took the assembly out but probably could do it while in the gun. I think the trigger is a "little" smoother now.

Wait that's great to hear. The fulls size just got added to the roster so I've been looking at ways to remove the disconnect

I have a one-month-old RM1C with the performance trigger upgrade. The performance trigger lacks the magazine disconnect feature. Here’s a picture of the trigger bar for your reference.

Where’d you get the performance trigger from?
