Easy install and not too flashy, i would give it 5 stars if it fit flush to the maxwell - Tyrant CNC Sig Sauer P365 X-Macro +3 Magazine Extension

From the two mag extensions I purchased this one was easier to install, but it does not fit flush when the mag is seated into the P365X Macro. There is about a quarter inch gap. Possibly if I get a flared Maxwell it may cover up the gap, but I have another Mag Extender from a different brand that fits flush without a Maxwell. So keep that in mind when purchasing this one.
