Santa brought Brian a Western Arms gas blowback replica of an SV Infinity 5”:

Thrown in a CED Air Soft timer, and some 1/7th scale USPSA steels and plate rack to make a complete training system in garage, basement or backyard.

The system uses “green gas”, which is basically propane without the scent. One $19 tank of actual propane and a $5 dollar tube of silicon oil will keep him shooting for a few thousand airsoft shots.

The system blows back the slide and is an exact replicate of an SVI Infinity 5”. They fit in my 2011 holster system and the magazines fit in the magazine holders on my belt as well.

Once we sorted it out (the manuals are in Japanese) we found it quite realistic and very accurate.  Using a USPSA target sized to simulate 20 yards, he got 1.30 second draw to A zone hits in our first tests.  Hitting pop cans at 15-20 yards is no problem. We have the system dialed down a bit now, but we can rev up the gas it uses to better simulate recoil.

Driven by the popularity of airsoft IPSC in Japan and Asia, there are many after market options for these guns.
