I use a couple of these on my reload mags for USPSA. DAA PCC Mag Grip

3.2 grains N320 147 Blue FP @ 1.125

I load them for several PCCs (MPX, MBX, Stern, Nordic, Scorpion) and pistols. Using 3.8 grs N320 or Titegroup. 1.10 OAL. Very accurate and they cut nice round holes.

Run them in several PCCs (MPX, Scorpion, Stern, MBX, Nordic) with very good results. 3.8 grs N320 or Titegroup, 1.10 OAL.

I load MG 124 JHPs @ 1.10 with 4 grains Titegroup or N320 for all my pistols and PCCs. Accuracy is superb, especially in my PCCs.

Green only, red is worthless in the day. Crimson Trace CMR 206.

" According to Speer/CCI Technical Services - Both the CCI 550 Small Pistol Magnum and CCI 400 Small Rifle primers are identical in size. Both primers use the same cup metal and share the same cup thickness. Both primers use the same primer compound formula and same amount of primer compound."

not when you try to add them to the cart...

Stern makes an add on magwell.

I run the Stern Defense magwell conversion and their 8.5 inch upper on my LMT SBR lower. Super reliable and accurate.

Definitely do not loosen the mag release, could cause mags to drop out under recoil. As suggested download a couple. Also practice loading with the mag full (at whatever capacity minus two) to get used to seating a loaded mag. Also watch the angle of the mag, keep the front level as the can be a tendency to drop the front. I use the “beer can” grip on the mag, it’s not like a pistol mag.

I run TTI +11 for most things. I use the 30s for reloads as there is more to grab than the 20s. I have only used the 20s for benching loads.

Over 15,000 trouble free rounds though my Gen II MPX. I have shot nothing but 124 PD JHP and 4.0 grain Titegroup. runs like a sewing machine. I have observed most troubles are with people running super lite loads, coated bullets, or messed with the springs/ports. I ran with the original extractor/spring for the first 12,000 rounds. I run a BCM spring/insert. The donut added too much tension.

I put together a Spike's lower with the SBA3 brace and a Stern Defense conversion and Stern 8.5 inch upper for a home defense pistol. Using an Aimpoint T1, Crimson trace laser and light. I currently run Winchester 147 Silvertips, which are low recoil and low flash. Unless you run suppressed, pistol caliber works fine, look at the millions of subguns used effectively for decades.
