I'm new here and just beginning to navigate, so if this has been covered please forgive any redundancy

I have new 365 ( very impressed )
I purchased 2 12 round SIG Magazine, from two different retailers. I also have a Makershot
speed loader.

I have loaded both and struggle to get the 12 round in, I have managed, but with the 12th round loaded
neither Mag will seat or lock , if I remove the 12th round they inserts as normal...

I have not found any mention to this , both Magazine are Factory SIG parts.

Thank you for the reply ...

Im familiar with search , had not found it here though, your guide was helpful.

I had attested the issue was stiff mag springs
may also be the Makershot loader I have for the 365 . I also had the stiff loading last round with my 10 round OEM Mags however not the problem of the 10 round mags inserting.

So I ordered an Maglula UPLULA loader.
Beside it will save my thumb for my 1911s

If the slide is not locked open, it can take a good bit of force to seat a full mag. You won't break them.

Welcome to the forum!

Just a friendly tip since you are new:

Admin prefers descriptive thread titles and will generally lock one that is vague. An edit may be in order to start off on the right foot.

^^^ Yup.

Descriptive title ,as suggested
Subject has been altered
hope this meets approval

BTW the Mag feeds through flawlessly

ALL those itty bitty mags are a PITA at first. I had a Glock 30 that darn near needed a hydrolic press to seat the last round initially.

Load it and let it sit for a week or so.

Load mag from slide lock or give it a FORCEFUL seating.

It will loosen up.

Thank you for the Maglula UPLULA loader Tip.
I was not familiar with them.
It made all the difference, the issue I was experiencing was solved...

This Sig is my first... " compact Modern double stack "
all my other Semi Autos
are 1911's WW1 Lugers WW2 P38 and Beretta's

My P365s magazines were impossible to get more than a few rounds in manually when new.

I used a Maglula loader to load them to capacity (10rd, 12, rd and 15rd) Once loaded they worked fine.

AFter loading them to max capacity I have let them sit loaded for a couple of months now... I used one at the range this morning and discovered they are much easier to load now... not yet to the point I can easily load them to capacity manually, but much improved... I think a few more months will solve the problem.

FWIW
