If i could have only one Glock gets my vote, in .40 or .45 caliber. Glock is dependable,accurate at all defensive distances,very easy to maintain,will digest any ammo put through it,parts are cheap and accessible . If memory doesn't fail me there only 32 parts to the whole gun, that includes slide,barrel grip frame ,sights,pins,springs etc. They are made to function in the harshest conditions and will shoot underwater. The newer models have changed grip styles to accommodate smaller hands. Also there are after market accessories available to tinker with,oh yes Glock has excellent customer service available if needed. Now if we are talking long range hunting or precision target shooting i would prefer a well tuned long barrel revolver. Almost forgot,desert eagle makes an excellent boat anchor,just my opinion.
