This tool has a large and wide cutout, needed to support the firearm correctly and easily, to avoid tipping of the slide which can destroy it. Others have a thin cavity which enables slide tipping.
We have added lots of new additions to the tool.
DON'T BE FOOLED BY COPYCATS - that claim to have developed this tool or sell at a cheaper price. There is one sold on eBay & Amazon that is a COPY!!! You get the quality that you pay for! Cheaper doesn't always work, if you want a quality product, backed by excellent service, years of experience, and a tool that will last as long as your firearm this is the tool for you.
