Fondled one of these yesterday. Nice pistol but somewhat unremarkable. Made in Dallas TX supposedly in conjunction with AREX of Slovenia.

MSRP is $460 the LGS here wants $450 which IMO is overpriced.

Mags available from RM's website for $24.95

Impact Guns price is $400.  Some other vendors have them priced as low as $355 which I'd do.

We just got one at the range yesterday for a rental. Fingered it a little bit. Trigger is scratchy, and I'm not all that impressed with the reset. I'll run a box of ammo through it and report back as soon as I get a chance to do so. Stay tuned........

Primary Arms has the RM1C in three different frame colors (black, grey, and FDE) for $359 + tax/shipping

They also have 15 and 17 round magazines for $15.95 each

I love my Arex Delta M Gen 2 so I see no need for the RM1C but it would be cool to have Dallas, TX on my slide

Ok, finally got time to shoot this pistol. As I said before, the trigger is stiffer and scratchy in the run up to the break than I would be happy with. That being said I suppose with some judicious polishing it could be made nicer. Gun shot into about 2 1/2 inches at 5 yards which is acceptable for a quick function test. Zero malfunctions of any kind which is nice as well. Sights are easy to see work well. Grip ergonomics are comfortable and it fits my hands well.
It did seem a little bit snappier than I expected given it's size and weight. I would not be in the market at $400+, maybe at $325, given my observations with it. With a cleaner, smoother trigger, it would pass muster for me. But just not my first choice. Ymmv


ETA: Reset was ok, if a bit indistinct.

I think that thing was failure from day one.  

Within a few weeks of it being available, there was a local on here selling it for just above $300 if I remember correctly.  I don't believe it sold quickly.  

There's too many proven designs just to give money to yet another company who's putting their name over something built in Europe.

Arex did a nice job with the Delta series, listened to feedback, and delivered an excellent value.

This is basically a Delta that's more expensive. I don't see the point.

There is no point.  Forget it exists.  It's a flop

My local go to gun shop has 'em priced at $399.00. Don't have one in stock but I'll find one laying around to 'fondle' It "seems like" a good useable pistol for my south pawed, arthritis infested hands!

I see you live in MD. Wouldn't it be difficult to buy one of these in your state as Rost Martin doesn't make 10rd magazines only 15 and 17 rd?

(yes, I know that MD does not ban the possession of these mags only the sale...that you can legally physically buy them out of state and bring them back across state lines)
