The German company SIGG, who developed the double-pistols I recently blogged about, are well known for their FSSG drop-in full-auto selector switches for Glock pistols.

This small selector switch replaced a Glock’s rear slide plate. It allows the selection of full-auto or semi-auto fire and is compatible with any Glock. The rate of fire can reach 1200 rpm depending on the ammunition being used.

How much fun would would a 10mm Auto chambered Glock 20 be on full auto ? Watch to video below to find out …

eGun.de is currently auction off one of these switches for about $280 (202 Euro).
