Well I think there are plenty of great guns out there these days. And anything made by man is going to have issues from time to time specifically when an item such as a firearm is dependent upon a variable such as ammo and maintenance.
Here's a few things I found with regards to Sig Sauer;
…If you have a SIG SAUER P238 with a serial number between DA000501 and DA003216, please cease use of the firearm immediately. Not all P238s within the identified serial number range are affected; therefore, it is imperative that you contact us via the UPGRADE HOT LINE at 1 (866) 446-1914…

Slide Fracture
This isn't supposed to happen with a solid steel forged slide
A report from Switzerland concerning a major slide fracture in a SIG Sauer P229 in the area immediately at the forward edge of the ejection port…
I send you this warning about the use of the mentioned pistol series. If you own one of them it might be a good idea to check with SIGARMS or your local dealer. I am not sure if this may also occur in the U.S. or if this is limited to the European market.
This particular event with 9 X 19mm SIG Sauer P229, Serial Number AL xxxxxx, (both slide and frame of German manufacture), happened in mid-August 2003 at the shooting range used by the Federal Office of Police in Switzerland. As the Range Master in Charge when it occurred I took the above photographs of the slide so you can see what happened and where. Ammunition was standard Swiss military issue, 9mm ball (Pist Pat 41¹) and there weren't more than 300 rounds through the pistol.
In September there were two more pistols with broken slides. One fractured completely and injured a female police recruit² in the chest (a lucky "punch" for point shooting). Fortunately the officer wasn't hurt badly… it was just a bruise on her chest.
The response of SIG Sauer representative SAN and the Sauer rep from Germany was that they were willing to exchange, under warranty, the slides on that entire series of pistols.
The investigation brought out that it wasn't a problem with materials but a manufacturing defect stemming from too sharp an angle³ at the forward left corner of the ejection port. We've found that quality in general deteriorated with SIG Sauer in the last couple of years, basically since the arms factory was sold from Switzerland to a German owner.
Make sure that you check all SIG Sauer P229 9 X 19mm pistols before using them…. there is already one injured police officer in Switzerland, and I think that is enough.
SIG-Sauer has been known to experience slide "toughness" problems in the past, but those were almost exclusively with the Navy's P226s issued, ironically, in the wake of the problems with the catastrophic slide failures of the Beretta M9s. The SEAL Teams's P226 slides were, according to one retired Special Operations officer, "beefed up," and are identified with an anchor marking. In addition, unspecified problems have recently caused a total of 41 Model P229s in 357 SIG to be removed from the Federal Air Marshals program.
A source familiar with the SIG product line looked at the images and agreed to follow up on the matter.
All P229 slides are CNC-machined from a solid steel forging, regardless of caliber, .40 S&W and 357 SIG as well as 9 X 19mm. Other SIG P22X models used slides of stamped metal. But an interesting fact came to light during this investigation: there is a different "cut" in the ejection port area in the European version, although SIG's engineers say that this is not the cause of the problem. The fractures, they say, appear to be an unusual combination of a materials problem and a process problem that should not recur.
As a precautionary measure Sauer is now making new slides for the Swiss agency, and is performing a type of magnaflux process to make sure this "cracking" does not recur.
I came across more than expected since Sig Sauer is one of the best handgun manufacturers around. BUT my point is that ANY firearm is bound to have issues. And the more plentiful a supply of any one brand that's out there, well the law of odds and averages says they will show more issues. So naturally Glock may have more reports of issues because there are tens of millions of Glocks in circulation. I like both manufacturers as well as HK; Beretta; B H-Power; and a ton of others. So I can't really "dog" a Glock over a Sig or a Sig over a Beretta or an HK over...
