Sig P250, homemade possible?

[Guns R Tools]

It seems that receiver which contains serial number is rather small compared to traditional pistol thus possibly easier to machine.

If someone can machine the receiver and buy all other parts, grip frame, slides, barrel, trigger etc. does it qualify as home-built?

[bwiese]

Why waste time doing that crap?

We'll be NeRFing them soon since frames are not Rosterable.

[NeoWeird]

Besides, small is usually HARDER to manufacture as you have less to hold and in tighter spaces. Also, Sigs tend to be COMPLICATED as hell, and from what I've seen, the P250 is even more so. Besides, without one to replicate or a print to go off of, it's not exactly a walk in the park. Reverse engineering alone is hard enough when you have all the parts, but when you're making from scratch....well you might as well make EVERYTHING from scratch.

[loosewreck]

NeoWeird is totally right, I have experience with modeling and cad programs, and even with the original part to reference it's still very difficult to replicate a part to the right tolerances.

amen to that, i replicated H&K forward assists that are on the PSG-1 and HK21 and it took me 1 month to get all of the measurements right and set up jigs to hold everything.

the problem with actually measuring something is that depending on its complexity there are just certian angles and dimensions that you are not going to get without creating some sort of special jig with known starting dimensions.

take for example the chamber of a rifle say .308 now sure there are alredy dimensions out there. lets say theirs not and you want to reverse engineer it.

so you make a precision cast of the chamber so you can measure it, thats the easy part. your not going to be able to just take a pair of calipers and get a perfect copy onto a print too many variables especially where the chamber tapers down. you have to think of creative ways to get it.

its not impossible just time consumeing and in the realm of machineing time consuming = money lots of it. :)

that being said if anyone gets one of the P250 frames, i would be happy to reverse engineer it and make a cad file. hell if you wanted one i'll let you push the GO button on my machine so you are the one who technically MFG. it :) well i dont know how well that would really work out maby not :(

[bohoki]

i was thinking the same thing but i dont know how easy it is to get the internals from sig(hammer trigger trigger barvarious springs and pins also how much is the grip frame /complete slide and barrel?

the little "frame" looks pretty easy to machine if you had one to duplicate although the part is a stamping

and so doesn't look like a gun you could probably make it in a machining class just call it a "precision drawer slider" if anybody asks

[bdsmchs]

The P250 will be one of the first guns I NeRF. It's very very high on my "want" list.

I'll let you take a look at the lock if you really want to try building one for yourself.

FYI, the conversion kits and frame's are not readily available yet. There's a couple conversion kits on gunbroker, but most places supplying the frames are backordered. It's still a brand new gun, so stuff isn't fully in the pipeline yet.

What's a lock? And is this in regards to the P250 or are you making an AR pistol with the frame? Sorry for the noob questions.

Also, is Sig planning to make some 10rd mags soon?

the gun is designed after the old saying lock ,stock and barrel


the barrel and slide are one component the stock is the grip assembly and the lock is the serial numbered reciever containing the framerails, slidelock and fire control mechanicals

The term lock means the lockwork of a firearm. It's the firing system, basically. Most "locks" these days are integral to the receiver, so no one really uses the term anymore. The new P250 has an independent lock that you can replace and remove from the frame. It's the lock that is the gun in this case with the serial number and all. Since the frame of a handgun is the receiver, and a receiver/frame is normally the "gun", it doesn't make sense to call the Sig P250 lock a receiver.

"Lock" is the most accurate term we have for the serial-numbered part in regards to this gun.

If you look at a black powder gun where the term came from, the lock is usually something that can be seperated from the gun all on its own:

Wheellock
Flintlock
Caplock
Matchlock

This discussion has nothing to do with AR's.

Doesn't matter. Don't really care. I'll have the factory mags shipped in as parts and build them back together as 10rd'ers.

You better be a hell of a machinist. But IMO the time spent to get the right tolerances makes it not worth it. Now unless you REALLY REALLY want to make your own gun. Personally I rather go buy one already made

If you could buy the rest of the parts, the P250 lock chassis would be pretty easy to make. It's just a trough of metal, basically. With some holes in it.

:rolleyes::rolleyes::rolleyes:

too each thier own :)


but it doesent look that hard, making the trigger componets maby a little because of heat treating and etc but in general even CNC'ing that frame you'd end up with a more riged unit.

Thanks for the clarification fellas.

The pic of the P250 with the stripped frame looks very easy to put back together compared to a totally field stripped Glock or HK. Much easier than fumbling with the little springs, screws, trigger parts etc to put the frame back together. It's all in one piece. This just might be the first NRF I'll be DROS'ing.

Just got to find someone to mod the mags to 10rds for me.

[bohoki]

gee that reminds me of the tokarev pistol hammer group

Why not do them yourself?

[DeeL2003]

Never tried it myself nor do I have a clue where to start. For some weird reason I thought it was illegal too.

What's involved in modding a mag to only accept 10rds?

[Turbinator]

I would think the only danger in modding your own mags is if your mod isn't seen as 'permanent' enough to constitute a 10 round mag that couldn't readily be converted to a high cap in seconds. The mods we've seen here usually involve pinning or epoxying a rod in place, then fixing the base plate, such that changing out parts to create a hicap wouldn't be too easy to accomplish.

realize that what you you are really doing is assembling a 10 round magazine

if you are modifying a high capacity magazine you have already broken the law by importing it

Not too easy? It's super simple. Make a block out of plastic. Drill a 1/8" hole in the plastic and the mag body. Install the follower and spring into the mag body, then the block. Line up the hole in the block with the hole in the mag body and then pop-rivet it into place. Cheap, simple, effective, permanent.

Then install the mag baseplate, epoxying it if you wish.

A harbor freight pop-rivet gun is real cheap and will last a long long time.
