So with 124gr RMR Match Winner bullets loaded at 1.095 I am getting a power factor of about 126-127 with 4.3 grs of N320. Too close for me to take a chance at crono. That was from a 4.7 inch Grey Guns slide in a Sig 320. I was planning on bumping it up to 4.4 Gr, but the VV lists the max as 4.3. Has anyone had an issue going to 4.4. I saw no pressure signs at 4.3, but figured I would ask here before actually doing it. Thanks

Only time my mags get cleaned is when I have to take a swim with them at a RnG match.

That looks slick.

Henning's won't work with a magwell unless you Dremel out the back of the magwell to fit the mag (the locking pin on the extnesion). I had to do it. Doesn't look the best, but works fine. 21 rounders work with no modifications.

Thanks

Thanks Ranger. I assume you meant 1.125 on oal

I purchased 2k of the 9MM 124 GR. RMR FMJ TRUNCATED CONE FLAT POINT MATCHWINNER BULLETS to try in my X5. I am looking for an n320 load that will make minor. Figured I would ask to see if anyone is using that combination to give me a starting point. Also interested in what OAL your using as well. I swear I saw a post on this, but of course I was unable to locate it. Thanks

Try the armory craft reduced spring kit. It does help.

Springer Precision makes one. I’ve been happy with mine. Fits a RMR foot print.

Thanks all. Great feedback, exactly what I was looking for. I am going to give Robert a call this week.

Anyone had one of TSA's carry jobs done on your 320? If so what did you think? I am considering sending off my AGX for one. Hoping that would get rid of lot of pretravel and smooth it out some. Not that it is too bad. FYI This is my RnG pistol and house pistol. Any feedback would be appreciated. Thanks

A buddy has one with a k on it. Runs fine with bulk. I’ll let you know on the RMR.

I just ordered a Plate from maple leaf to put a RMR on mine. Installs ok a little high as the slide cut doesn’t seem as deep. Haven’t had a chance to shoot it though to verify functionality

Had the exact same issue with my X5

MS processed brass in Indiana. I’ve never purchased their brass but have had good luck with processing through them.
