ATI/GSG Hits Bullseye with M1911 and Firefly


M1911: history in your hands

People who follow the Shoot ‘N’ Plink columns and videos know my passion for Browning semi-automatic pistols and my 1911-22 and Buck Mark. So, when American Tactical/German Sports Guns offered to let me try the Firefly for a second time, and the M1911 in .22 caliber, it was going to take a lot to win me over.

I decided to keep an open mind on the two pistols, even though I wasn’t completely impressed with the Firefly on the first go around. Once they arrived, it was love at first sight. The quality of the Firefly had improved immensely. It looked like the SIG Mosquito, which was the original model manufactured by GSG. As for the M1911, it looked like it would be great. However, the proof would be in the actual use of both.

New Firefly

This second one was a tan model. I prefer black, but tried to keep that out of my mind and focus on the pistol’s overall quality. Design-wise it has everything thing a person wants. It has an easy slide action, single/double action, slide release, easy operating safety, de-cocking lever, a quick teardown lever, adjustable rear sight for windage, three front sight posts (tall, medium and short), yellow dot sights, two slide springs (high velocity for above 1200 fps; low velocity for below 1200 fps), and an easy loading magazine for 10 rounds of .22-caliber ammo.

My setup was to use the medium front sight, which is factory installed. I recommend using this, if at all possible, as changing to one of the others will raise or lower the spot of impact by around 7.5 inches. It did not have to be changed, but the rear sight did need a slight adjustment.

Brass down the barrel

Ammunition was mainly CCI Mini Mag, CCI Standard and Federal HV Match and HV Hunter, with some Remington Thunderbolt. The Mini Mag preformed about the best. I couldn’t see a difference in the springs. Perhaps there was a mix up in this test model. The lower velocity is supposed to be marked with white, and neither had white. This was not a big deal, as it still shot nicely.

After a slight adjustment to the rear sights the Firefly laid most shots into the middle 4-inch area of the target. Close to the performance of the unadjusted M1911.

Heavy haul trigger

Shooting was great, but best in single action. Pulling the trigger for double action was a bit difficult, as the trigger pull was extremely heavy. I allowed two Scott County Conservation rangers to try it. They said the same. This was the only negative, but a big one if it was for a smaller person with less hand strength, and they wanted to use the double action.

The reach for the de-cocking lever is slightly difficult, but manageable with a slight canting of the gun to use the thumb to engage the lever. No huge minus for that. All in all, I would give the Firefly a strong 4 stars, and a full 5 stars for the improved quality.

This pistol strongly impressed me. The M1911 is like a full-size 1911 .45-caliber in dimensions and weight. Even most parts are interchangeable with a regular 1911. It has yellow dot sights, adjustable rear sight for windage, three front sight posts (short, medium and tall), lever safety, grip safety, slide lock, easy loading 10-round .22 caliber magazine and normal 1911 teardown. My unit had nice walnut grips.

As with the Firefly, I would recommend staying with the medium front sight. It worked great with that sight. The rear sight never had to be touched for adjustment. It is the first semi-automatic pistol I’ve held that did not need to be adjusted, hitting the mark right out of the box. Several rounds fell into a 4-inch area, with a lot of those hitting within a 2-inch area. Later, I fired at another target and drilled out the center area with a tight grouping.

Leading lead

Ammunition used was primarily CCI Mini Mag and Federal HV Match. This pistol definitely needs higher-velocity ammo to get it to cycle properly. The only problem encountered was with the magazine. Fully loaded, it would not fully insert unless given a harder tap than needed when empty. A couple of times it was not inserted fully, immediately apparent as the trigger won’t pull without the magazine.

De-cocking the weapon definitely takes two hands, one to pull the trigger and the other to grip the hammer for a slow release. This is actually a good idea to keep it even safer. The slight difficulty of inserting the magazine was not enough to deduct a rating star. In fact, I give few five-star ratings, but this one definitely receives five stars for quality, handling and overall shooting.

Top marks for manufacturers
