Promag Warning

Promag blowout text

One of our local shooters ordered some “Promag” after-market S&W M&P magazines recently. His baseplates soon started popping off, dumping ammunition and magazine parts everywhere.
We took one of his mags home for a little inspection tour — and while the basepads were correct, the magazine tube was roughly .030″ too narrow. 
Promag test text
We think this is simply a bad batch that got by the Promag QC people, so here’s the test:  Push the baseplate all the way left or right, and see if a gap appears between the mag tube and the inside edge of the baseplate.
If you can see the lower lip of the magazine — you’ve got a problem. Check yours right away!

Floorplate “spare parts” kit available

spares_kitWe just added an inexpensive “spare parts kit” to the store under “springs and miscellaneous.” Odds are you’ll never need these, but we get a few calls every year from people who lost a screw in the carpet, or sucked the retaining plate into a vacuum cleaner.  When you order, let us know what sorts of floorplates you’re using so we can send you the perfect set.

CX4 Carbine basepad improved

CX4_improvedWe’ve adapted the “hollow ground” process used on our HKP30 basepad retainer to the CX4 carbine (shipping today). Most pistol magazines protrude beyond the frame slightly, making it relatively easy to bolt on an extended basepad. The carbine’s and the HKP30’s magazines do not protrude, so our external retention system has to slide into a very narrow space.

Ruger Magwell Update

Just received our latest pre-production prototype on our magwell for the Ruger Mark III Hunter (22/45).  Hoping to have those in production in the first quarter of 2014!

 

Tinkering with XDM springs

This week we’re searching for an inexpensive spring for XDM shooters that prefer XDM kitlast-round slide lock over the +1 (but no slide lock) capability of the Grams spring/follower kit.  Turns out the factory XDM spring resembles the Glock spring — but with some important little quirks. Currently if you want the full +3  you’re stuck with the stock spring and its  “iffy” last-round lockback after 50 cycles or so.

Using a 140mm Glock spring gives you +2.5, and locks the slide back positively.
