I purchased two more - a 10 and a 14 - from http://gregcotellc.com/cart/ which I've found to have great selection, very competitive pricing and OUTSTANDING rapid service.
So far the function seems to be fine though I need to test more to be confident in that. The 14th round is a bearcat to load. I'm certain some will require a loading device. Inserting a fully loaded magazine into the pistol with the slide in battery (as with a tactical reload) it requires a firm tap to fully seat the magazine. There does seem to be an increased drag when working the action with a full mag on the first round and the next 13 feed more easily. It will take some testing to convince me this is 100% reliable - though so far, so good.
|14 round mag - Empty|
|14 round mag - loaded|
|Fully loaded Mag weight - 15.1 ounces|
|Empty Mag weight - 4.7 ounces|
|10 round Mag weight - empty, 3 ounces|
|Fully loaded 10 round mag weight - 10.5 ounces|
|The 10 & 14 round magazine will fit and function in the 45 Compact. 14 round magazine shown.|
The 14 round magazine seems to be a very nice option for a home defense situation. It would probably serve well as a secondary magazine when in the field or for competitions when capacity isn't limited.
