It's all together I had some leakage around the transfer port at first, losing 60+ fps on average with the steel breech. Luckily I got things sorted, passing the tissue test and regained original velocity. Now just have to sight in later. I want to give a big thanks to everyone who helped out, so Thank You. This pistol feels much better now, can't wait to sight in and get shooting. If this gun sees any changes it will be grips/pump handle upgrade and a solid pivot pin. Other than that it's perfect for me.
