Sig Sauer Mosquito - Sour Taste

The internet is always right… most of the time.

Last year I purchased a Sig Sauer Mosquito (22LR) for two specific reasons. First, I wanted to have a pistol that was easy to handle, reliable and not over-powering - so that my wife and kids could get accustomed to shooting. The second reason was to provide home defense since we lived a full 30 minutes from any police response.

The allure of the Mosquito is the compact size - scaled at 90% of a regular pistol, and ability to shoot 22LR - which is really cheap - under 10 cents per round. Several YouTube videos made the specific point that the Mosquito: is easy to handle, does not have much recoil, and uses cheap ammunition, which makes for a great training gun.

Over the winter we put several hundred rounds through the Mosquito, will deteriorating results.

Problem: Ammunition - Reliability and Availability

Several YouTube videos pointed to problems with Failure to Eject and misfeeds. Crappy ammunition was blamed. Our initial experience with CCI Mini-Mag showed flawless performance. Ammunition by anyone else, well, not so much. The availability of 22LR is a problem, and the availability of the good stuff (CCI) is even worse.

The spouse and the boy got used to clearing a misfeed, which is fine for the "training" part of our goal. After all, any pistol can have a misfeed or misfire which requires intervention. But this behavior is a total "fail" for home defense requirements.

Pointing a pistol at an intruder might discourage a few intruders. A single, well-placed round of 22LR might discourage a few more. But not being able to dissuade a motivated intruder by unloading an entire clip is a big problem.

Range Experience

Red's Indoor range has a lead control solution that requires cold outside air to be pumped into the range. The cold air flows from behind the shooting line down the entire length of the lanes. When it is cold outside, it's cold inside. And, when it was cold the Mosquito performed very well.

Once the weather started warming up, and once we tried to use less expensive ammunition, we started seeing the ejection and feeding problems. My cleaning routine does not leave a pistol wet… clean - yes, lubricated - yes, but wet - no. After two shooting and cleaning sessions in April, I am convinced that dirt (and lubrication) is not the issue.

Solution

I'm torn about the solution. We shoot 22LR in both the Mosquito and a Henry Golden Boy. Unlike others at the range, we often run through a couple hundred rounds -- for under $20. The ease of handling and low cost make range time very productive. But for home defense the Mosquito does not inspire confidence.
