Very solid and heavy pistol from this Taiwan manufacturer. The Caspain Hi-Capa 5.1 is based on Marui Hi-cap 5.1's design. Full metal construction with 20mm lower rails for installing accessories such as flashlight & laser unit. From the minute you rack the slide, you'll know you've got a serious piece in your hand. The blowback action and recoil add to the reality! Metal slide makes this pistol extremely heavy and solid with a strong kick during blowback.

This new custom airsoft 1911 weighs the same as the real 1911 .45 ACP. The feel of this gun is amazing. Constructed of metal both internally and externally.

A laser or flashlight can be mounted on the rail in just minutes! Includes 30-rd green gas magazine and manual.

Things I liked: Size heft and ergos are just like the firearm. Fun to shoot (when it works right).

Things I would have changed: Uses ALOT of gas. Safety broke, doesn't always lock open for empty mag, leaked gas (but I fixed it).

What others should know: Safety lever broke off right side. Sorry I boughtCO2 mag adapter- not many shots to a 12 gram. Uses a lot of gas. Now using propane, stinky. Would not buy this model again. Will sell and get Sig or KWA.

Things I liked: Fantastic quality. Alot of shot for one CO2 cartridge, about 90. Completely mad e of metal and accurate down to the last detail including functioning. All of the safeties work like the real gun, the slide cycles when fired and locks open on the last shot. Pretty good accuracy in that I can hit a 2"" x 2" target at 40 feet. This is my first Airsoft gun of this type and I will be looking to buy another.

Things I would have changed: I wish the CO2 magazine came with the gun instead of the Green Gas magazine. The magazines are a bit pricey.

What others should know: You will not be able to put it down once you start shoot and your wife will make you pick up all of the little white balls.

Things I liked: Operation is identical to the real thing (have used springfield, colt, para-ordnance, kimber). Excellent and rapid recoil and cycling. Light, clean-breaking trigger. Clean magazine release. CO2 or GG option a major advantage, personally prefer CO2 after having used both types of propellant, especially since all my other airguns are CO2 (bb, pellet). All metal a great advantage in realism, durability.

Things I would have changed: Slightly thinner grip - just a tad wide for my hands, which are fairly average sized; the grip is wider than a single-stack, though not as wide as a para-ordnance double-stack. May need better quality control or a slightly more robust design on the gas seal where it contacts the magazine - mine broke after just four co2 cartridges. Cover at the bottom of the CO2 mags is quite large, a smaller design would be good.

What others should know: Pyramydair replaced mine in just a couple of days, very cooperative and professional. Would make a great training device (even says for training use only on the box). Instructions are poorly translated, but diagrams help. The match to the real thing comes in great here - if you have used the real thing, you already know everything to do aside from the very intuitive CO2 replacement.
