I think its very important to be proficient in your own weapon but also to be able to perform with other's weapon as well. Whenever you go shooting with a group of friends, or have the opportunity to shoot MANY MANY different types of guns and manufactures, take the opportunity to see how other guns works, their trigger pull and ease of use. keep in mind the main steps of clearing a malfunction. TAP AND RACK. if that doesn't work, lock the slide and rip the mag, work the slide a few times and then tap and rack again. being bored and having many gun friends gives you a great opportunity to try this. and i bet its pretty damn fun too!
