The 308 Win caliber performed well at my local range, and the pistol felt balanced in hand. My only nitpick was the trigger pull weight – it felt heavier than I prefer for precision shooting. Still, it grouped consistently at 50 yards with Hornady ammo.

The pistol shot well with Federal and Winchester ammo, but I had a couple failures to feed with cheaper steel case. The 308 Win recoil was manageable with the brace system. For the price, I expected slightly better reliability across all ammunition types. Still a good option for California shooters.

I used this during a recent trip to field areas around Modesto. The compact size made it easy to maneuver through brush while maintaining the 308 Win power I needed. The Tailhook brace provided excellent stability when taking shots from awkward positions. It performed flawlessly in dusty conditions.

I took this to the range in Sacramento last weekend and was impressed with the accuracy right out of the box. The Tailhook MOD 2 brace made it comfortable to shoot despite the 308 Win recoil. After putting 100 rounds through it, I found it cycled perfectly with Federal ammo. This pistol handles better than I expected for something in this configuration.

I was skeptical about accuracy from a pistol in 308 Win, but this proved me wrong. At the range, I consistently hit steel at 75 yards. The Tailhook brace provided solid shoulder contact, and the overall build quality felt premium. It handled the heat well during extended shooting sessions.

The balance of this pistol surprised me – it felt natural in hand despite the 308 Win chambering. I put 200 rounds through it at my local range without a single malfunction. The Tailhook MOD 2 brace made a noticeable difference in control during rapid fire. Everything from the finish to the trigger felt well-executed.
