The ejection port has a semi-circular cut-out at the front and the bolt has a single hook extractor. The hammer has coarse hand knurling on the spur. The two-piece walnut grips have a varnished piano finish. The barrel, cartridge elevator, rear sight and bolt are blued. The hammer, trigger and lever are color casehardened and the frame has a natural brass finish.
