The KelTec PMR30, introduced in 2010, is a unique, lightweight, 30-round .22 WMR pistol designed by Tobias Obermeit to bridge the gap between .22 LR pistols and more powerful centerfire options. Based on early 1990s Grendel designs, the polymer-framed, hybrid blowback/locked-breech pistol saw early production tweaks to improve accuracy and reliability, establishing itself as a popular, high-capacity "plinker".
