There are many examples of guys on this forum, after having bought a gun that there aren’t many of in SA, asking where they can get spares and mags etc.
Being harsh sometimes gets the point across that there are few options for a full defensive firearm package that make it easier to keep the gun running.
While the OP has voiced opinions and also accepted some good advice there are many new guys who come on the forum and frankly don’t listen, which is their right.
The wealth of this forum is that there are guys who have been there, done that in terms of buying firearms and have gone through the missions of changing guns.
