MasterPiece Arms is venturing into the “multi-caliber” pistol market with their new “Defender, Machined, Grip” series.  While it has a decidedly 80’s “MAC-10” look to it, the modularity really gives it some flexibility.  I do really like that it accepts a standard Glock Hi-cap magazine.  It will be interesting to see what the consumer adoption of this style of firearm does over the long term.

From the Press Release:

MasterPiece Arms (MPA), manufacturers of the MPA MAC Line of semi-auto pistols, carbines, suppressors and MPAR Rifles, proudly announces the MPA30DMG, the first “multi caliber” pistol from the new DMG (Defender, Machined, Grip) Series. This 9mm pistol is based on the 30sst, but includes a fully machined aluminum pistol grip. The DMG series grip is MPA’s most ergonomically designed grip system allowing the ability to change calibers by changing the grip housing, bolt and barrel (depending upon the caliber).

The 30DMG ships as a 9mm, using a GLOCK® style magazine; however, by changing out the grip housing, bolt and barrel, other calibers can be fired using this modular system. Additional calibers in 5.7x28mm, 9mm, .40 S&W and .357 SIG kits will be available. MPA is working on adding the .45 ACP as a possible caliber and plan to have it developed potentially by SHOT Show 2015.

The MPA30DMG also includes additional upgraded features, such as adjustable front and rear sights, L-Bracket with QD plate for single point sling system and a Cerakote Flat Dark Earth coating. It is also available in Black, Gunmetal, Tungsten and Burnt Bronze Cerakote finishes. The pistol is further equipped with a side cocker, scope mount, lower Picatinny rail for flashlight or laser systems, hammer with disconnect (plus original hammer) and comes in an MPA polymer case.
