01. What's the difference between all the models?

The primary difference among our 23 Gauge Headless Pinners is the maximum fastener length the tool can drive. 1-3/16" for the P630, 1-3/8" for the P635, 1-3/4" for the P645 and 2" for the P650. All these tools can drive pins as short as 3/8". Beginning with the P635, new features were added and carried out for all subsequent models. These features, not found in the P630, include rear exhaust with silencer, no-mar tip, stepped magazine, large fastener viewing window, and spring loaded magazine latch. In the two larger tools, the P645 and P650, there is also the option of the Auto Lock-out feature which prevents empty (dry) firing and alerts the user when reloading is necessary.
