CAA Micro RONI Stabilizer

The CAA Micro RONI is the compact clamshell that defined the pistol chassis category. Its instantly recognizable PDW silhouette wraps an unmodified Glock in a polymer shell with an adjustable nylon stabilizer arm, an extended top rail, and side accessory rails. The pistol drops in without any permanent modification and locks in place, so the Glock returns to standard carry in seconds.

The Stabilizer version trades the older Micro RONI stock for an adjustable arm brace that enables one-handed fire while still adding the support and sight radius that make a converted Glock easier to shoot. This Gen 4X SKU is the Glock 17/19/19X/22/23/25/31/32/45 fitment; Roni sells the Gen 6 G17, G19, and G45 as their own model option, and the compact G26/G27 and the CZ and Beretta hosts each get a dedicated shell. The familiar layout keeps the Glock magazine release and slide accessible, which shortens the learning curve compared to the bullpup options.

The Micro RONI is the original that the rest of this category answered. It carries a higher price than the bare-bones stabilizers and a polymer build rather than aluminum, but the integrated rail real estate, the stabilizer arm, and the proven clamshell design make it the benchmark compact Glock chassis.
