STI firearm with Limcat slide and compensator
 

Comments: This airsoft gas blow-back pistol is made in Japan by Tokyo Marui (TM). The airguns in the Hi-Capa series are replicas of various STI pistols, which are popular with IPSC competitors. The basic Hi-Capa 5.1 comes with a plastic slide, which requires the use of duster gas. Using a higher pressure gas will crack the plastic slide. One of the first upgrades usually performed on the TM Hi-Capa 5.1 is to replace the plastic slide with a metal slide in order to use higher pressure gases. Using a metal slide and higher pressure gas also requires upgrading the recoil spring and hammer spring. Removing the slide provides access to the adjustable hop up control. The trigger on this gun is two-stage, with the first stage being very short and smooth and the second stage having a crisp break. The addition of a compensator and longer barrel improved both the accuracy and muzzle velocity of this gun. With all the modifications made to this gun, it has excellent balance, pointability, power, and accuracy and makes for an excellent Open Division race pistol. The original gun was purchased from UNCompany in Hong Kong. For information on the unmodified Tokyo Marui Hi-Capa 5.1, click here.

Review of the TM Hi-Capa 5.1.
Exploded Part View of TM Hi-Capa

Performance: Measurements were made on 02/22/09 at a temperature of 74 ºF and 14' elevation. A ten shot string was fired from a bench rest at 15' using KSC Perfect BBs (0.25 g), Tanio Koba Hi-Flo valve, and propane gas. The highest velocity measured was 338 fps and the lowest was 327 fps (average of the 10-shot string was 330 fps, s = 2.5). A five shot string fired offhand using a red dot sight, KSC Perfect BBs (.25 g), and propane gas grouped at 0.33". Click  the thumbnails below to see larger images.

Left Profile 2: Due to the short-stroke kit, the slide does not go back far enough to lock back. The back part of the rear sight has been removed in order to mount the AIP cocking lever.

Removing the slide provides access to the adjustable hop- up control.

Turning the hop-up control counter-clockwise increases the hop.

Loading BBs: The BB follower (spring) must be held back by your finger when loading BBs into the magazine.

 

Packaging: This photo shows the TM Hi-Capa (Limcat) as it arrived from UNCompany in Hong Kong (the safety levers, slide stop, and mag release were added soon after receiving the gun). The Shooter's Design STI grips were replaced with the original TM grips to keep magazines from slipping out of the gun. The King Arms red-dot sight and Shooter's Design sight mount were replaced with a Walther red-dot sight and a frame-mounted G&P scope base to improve accuracy.
