A few things every new Steyr Pistol owner should know:
1) The Steyr has to be well cleaned and requires slightly more lubrication than a Glock (if thats what you're used to). There is an excellent cleaning tutorial on this website with nice color photos and step-by-step directions. Follow it and you'll be in business
2) The Steyr likes decent quality ammunition. We all favor WWB or CCI Blazer Brass. Stay away from reloads until you're firearm has been broken in (500 rounds) and you really know what to look for in a reload. Mr. Apathy is the best source on what the Steyr likes for reloads on the Planet and we're very lucky we have him so if you're into reloading talk to him. Stay away from WOLF ammo at all costs as in my opinion it is just too dirty and the quality control isn't up to par with WWB or CCI. Now, some folks put WOLF through their Steyrs all day long and don't have a problem, but I've seen TONS of reports about FTE or FTFs that were the result of using WOLF.
3) You need to have a proper grip you can't limp wrist the Steyr and expect it to keep firing time and time again. Proper grip is discussed in the shooting tutorials posted by IDPASteyr who is a competition shooter in IDPA with thousands of rounds and plenty of victories with the Steyr.
4) If after cleaning it, using proper lubrication in the right areas (ie. don't lub up the striker pin or channel), giving it proper ammunition, using proper grip, and sending about 500 rounds down range it slips up and give you problems then send that puppy back. Mass production means that some things are going to come off the line not as they were intended. Steyr has awesome customer service, they've really gone above and beyond for folks. Mention you're a member of Steyrclub.com they know us.
GOOD LUCK, I'm sorry to hear that you're having problems, but don't let it get you down or scare you about this new pistol as I'm sure you can work things out and end up very happy with it.
