From The Truth About Guns:

Compact yet powerful, the pistol packs in 11+1 rounds of the popular 10mm round. Featuring fully ambidextrous controls, the excellent META trigger, removable short flared magwell and much more, the new XD-M® Elite 3.8″ Compact OSP 10mm harnesses fight-stopping performance in an extremely capable CCW-sized package. With its extended magwell removed, the pistol can also accept full-size 15-round magazines with backstrap-compatible grip sleeves.
