SR-SP GBB [SRC]

Very good replica for the price. Good materials and operation, and excellent tune-up, preparation and delivery times from TaiwanGun. A small issue in my unit: the magazine ejection button does definitely require significantly more force in the left side than the right side, but not a big deal.

A very nice product from SRC! The quality is very good. The decocker works, the safety as well. I got it in a plastic case. Also, it comes with an rail adapter already installed (so you can use underbarrel flashlight). It can hop 0,30 bbs with no problem - it could lift even heavier bbs as well. Hop is easy to set: pull the slide back just a little bit. Then you'll need to look from the top down into the ejection port. On the left side (between the slide and the outer barrel there is a small lever/wheel. Adjust it back or forward for setting the hop.
Magazines don't leak, with 0,30 and hop set it was shooting around 0,9J with propane (green gas).
The only negative is the magazine design. The bb channel is too wide and the bbs get stuck inside the mag and the pistol missfeeds/dry-fires. You can fix the mag by removing the feed lips and the follower. Then use nail polish or epoxi glue and put it on the left and right side of the bb channel (that will make it narrower). I did about 10 layers of nail polish on each side and that made it 99% more reliable.

so far only used it twice in the field but it works perfectly.
green gas is very snappy and efficient (2.5-3mags per charge in a 15 degrees weather), it also shoots very accurate with .25g bbs.
sometimes it misfeeds from the magazine when you dont stack the bbs neatly.
other than that it feels solid and works really well

Amazing pistol for the price! It's a 1:1 clone of the Tokyo Marui, so if you need spare parts, or if you want to upgrade your TM one with a metal slide, this is perfect!

Since this pistol is CO2 ready, I used 14KG gas on it and it's wonderful. It shoots a bit hot on gas, but it's just within the limits of my country limits.

Would buy it again 100%

Pros:
- snappy action using green gas
- accuracy is good within 75ft (using .32g bbs)
- quality of the Sr-Sp is phenomenal
- gun came with a hard case (I have seen some just come with a SRC cardboard box)
- parts are easy to source
- interchangable with most TM Spec USP-9 parts (especially if you want a threaded barrel for suppressors)

Cons:
- only comes with one mag
- bbs tend to get stuck when feeding sometimes and will have the gun dry fire until you force the bbs up
- green gas lasts for about a mag or two.

Overall the gun is a great buy if you are looking for a sidearm that looks cool and works great. I have tested the gun using .32g bbs and with the green gas mags, (SRC also sells CO2 compatable mags, but it damages the gun as the parts are mostly tm spec)

The mag feeding issue could possibly be avoided if you use lighter bbs as they are not as brittle.

This replica is great.
Only is to bad in didn't got the picatiny rail.
But overal is its a solid piece for this price.
The feeding is solid, the blowback is solid.
I recomended a friend of mine and he also orderd one.

I was honestly incredibly surprised and how well this USP replica is made. It's not horribly expensive, and it hasn't blown up in my hands yet. It has a decocker and the barrel tilts when you rack the slide. Everything is as it should be. It doesn't have HK markings, but it's certainly a good sidearm. Also if you find that it lacks power, try buying a C02 mag for it.

Before hand i would like to state that we have bought a lot of stuff of the taiwangun website. This replica in particular i very well made, it support co2 and green gas magazines witch are very good and dont leak ( I would still advise you to lubricate them before use with silicone oil). Performance wise its a bit all over the place that meaning while you have a much more of a kick with the co2 filling the bbs are going all over the place. It takes a few shots until the bbs become precise.

My favorite pistol so far, i use GG and Co2. ( my team has 5)
The feel,looks and quality of the pistol as a whole suprised me in a positive way.
on Co2 it shoots +- 1.8joule
Greengas 0.8 joule
After adjusting airnozzle both co2 and greengas shoot 1.1-2 Joule
after the hop is broken-in( rough it up a bit with 600-800 sandpaper) it responds well to hop adjustments. Range is good, especially for a secodary.
The recoil is powerfull and the pistol feels accurate, it suprises me how efficient the pistol is on the field everytime.

Some Cons are:
You need to load the bbs in the magazine correctly otherwise the bbs tend to jam. so load the bbs in 2 nice rows.
bigger problem is spare parts, there arent any to be found. and taiwangun.com doesnt carry extra parts either. the spring in the airnozzle base can come out and get eaten by the gun and then you are done shooting.
it happend to 3 guns already which i was able to fix with some handy work and some goodluck, but replacing the spring and the lost spring guide would be a better option.

I just love the build quality of this! Wouldn't have expected such from SRC. I also adore how crisp, metallic, loud and hard kicking blow-back it has. In terms of the show it makes, flawless. Some say it is fully Marui-compatible, but that remains to be seen, at least for me. For a basic pistol, accuracy is adequate, but you might want to change the hop rubber. Factory magazines might need a little sanding here and there to feed properly (one of mine's had little burrs in the feeding ramp). Upgrading the pistol would be a pita, even if it is Marui compatible, spare parts are hard to come by and enhanced parts are pretty much non existent. Mind you, this pistol has a TAC(tical) version, which has a 14mm threaded barrel, but it is not an easy task to get one, or only the barrel itself.
