SIG PM400 was created by jtallen83

I went and did it, grabbed a Sig PM 400 this morning. Got it with a couple P-Mags and 100 rounds for just over $1200, it better be reliable! It is cleaned, oiled, and greased now, ready for a test run this afternoon. I'll report back when I have some rounds down range. Still waiting on the Eotech for it.

So far so good. :twothumbs: 70 rounds of Federal XM193 Ball and no glitches. It drops the brass all in a neat pile about 2 foot across. The first target is what I called good for sighting in;





The cows were grazing our usual range so this was from a sitting position with a skinny tree for a brace in 20+ mph winds at 25 yards. I'm looking forward to getting the Eotech, my eyes just don't work so well with the iron sights anymore. I ended the session with 30+1 at a fairly brisk pace and was pleasantly surprised I kept them all on the paper;





I hadn't seen this model advertised yet on the Sig website but I liked the idea of having a gas gun with standard AR-15 parts and a lifetime warranty. It must be a fairly new offering, my serial number has a bunch of 0's before a 12.
The "brace" holds steady at whatever position I place it in. I did find it very awkward when strapped to my arm, hard to get a decent sight picture. It worked very well in the "Don't do this" position :naughty: , no problem getting a good cheek weld. I haven't put a sling on it yet but it has lots of optional attachment locations, any suggestions on the sling and hardware?
There is a bayonet lug but that would seem to defeat the purpose of the short barrel. It has an ambidextrous magazine release that works well. The trigger was a bit heavy but with a real crisp break.
I still have that Armalite SPR Mod 1 on order but I've been told it is an 18 month wait. In the mean time this will be a fun little gun! To bad I can't put a bipod on it, :naughty: stupid government rules! :usa:

Put another 200 rounds through the pistol/rifle today. No malfunctions and even the rookie shooters were hitting with the iron sights! :twothumbs:
Beside the standard 55 gr. loads I ran the 62gr. green tips and a box of 45gr. varmint loads, dropped all the cases in a neat little pile. I'll try some heavier stuff when I find it and do some accuracy comparisons when I get to a good range again.
I'm finding it about impossible to shoot with the "brace" as it is advertised but otherwise it has quickly found a groove for me. Sig redeemed themselves for me on this one! :usa:

A little more practice and I came up with this group;


45 yards from a picnic table with a range bag for a rest. I threw the one but with iron sights, 55 gr. Federal ball ammo, and my poor eyes I'll take it all day! It's a pistol :whistle: :usa:

Yeah... Rules...

I saw a guy with one of those cuffs attached to an AR pistol at the range a few days before we left. He was using it like a really short stock.

I can't help but wonder: Does putting the end of that arm brace up to your shoulder make the pistol into a short barreled rifle, in the eyes of the ATF? How stupid would that be? How are there still restrictions on SBRs?

Nice group, by the way. Certainly better than I remember doing with an AR pistol.

I'm not going to ask the ATF myself but, everything I've read says that how I use the "pistol" doesn't matter, they judge by the intent of the design. If you choose to fire your S&W 500 from your shoulder it would still not be considered a rifle. It will be interesting to see if the gun nanny's catch on to this work-around SBR and shut it down. Hopefully Sig has some good Lawyers that can hold them off.
I tried it strapped to my arm, my joints are just not made to twist that way, not even close! Maybe if you held it sideways ghetto style you could get a sight picture.
I had also read I couldn't put a bipod on it but I keep thinking of all those rifle caliber single shot pistols I've seen with bipods??????? I hate all the grey area but love the "pistol" :usa:

I shot mine one handed, holding it up at eye level. I had the benefit of a red dot sight though. I think once the ATF figures out how many people are using it "wrongly," there's going to be a "problem." ...or maybe not.

That's OK, I bought it with the idea that it would be a fine weapon to defend myself with against a tyrannical government! :usa:

I've seen S&W 500's and .460's with a bipod on them, not to mention TC pistols out there with bipods. That's not saying it's ok with the fed, just that people have been putting bipods on pistols for a long time.
ArmaLite Super SASS for sale W/ extras. PM for details.
