The Sig P365XL. The last couple years we have seen a surge in demand for smaller and easier concealable pistols. Although there is nothing wrong with small pistols, as with anything, there are trade offs.
Newer handguns such as the Sig P365XL are an attempt to minimise the trade offs but still keep size down to an acceptable minimum. Glock has also attempted the same with the Glock 43X and the Glock 48 (the subject of another post). By all accounts, both Sig and Glock (and a number of other manufacturers) have been successful in balancing out this compromise.
The Sig P365XL, Glock 43X and 48 are available in our store.
