This is a must have tool for p-series sig pistols. - SIG SAUER Armorers Tool Sig Combination

There's not a whole lot you can say about it except it looks like it ought to do the job. It's intended for multiple uses when disassembling Sig P-Series guns. You really need it for some disassembly jobs. It looks well made and yes, you could use a group of other tools instead of this multi-tool but this thing is an all-in-one.
