Polymer 80 PF940
The Polymer 80 PF940C frame is the ideal way to build a clone of a Glock™ 19/23/32 series of pistol. Any parts that you use must be for Generation 3 pistols, as that is what this frame is based on. Parts from newer Generations, such as the Generation 4 and/or 5, are not compatible with this frame.
The Polymer80 build requires the least tooling out of any of our builds. A punch set is handy for construction, but it is not required. What is required, however, is a rubber or non-marring mallet/hammer of some sort to put certain pins in the proper position. The only other thing you would really need is some fine grit sand paper and files for touching up certain areas, if deemed necessary.
One consideration, however, is the slide. If you wish for your firearm to be fully clean of serial numbers, it may be good to look into aftermarket slides and barrels. Factory Glock™ slides and barrels have serial numbers for compliance in European markets.
