1. No I did notSince we don't know you, I will ask a few questions and give some advice before you send it back.
1. Did you clean the gun before loading? New guns are shipped from the factory with a rust inhibitive that can become gummy over time. Cleaning and lubing the gun may solve your issue.
2. When you loaded the mag, did you load it full? Was it difficult to load the last round? Ruger mags are notorious for having very strong mag springs. I usually limit my load to 5 rounds in the mag for a while until that spring "breaks in" a bit. Once you have done this about 20 times (100 rounds), it should be easier to load and more reliable stripping the first round.
3. By your description, it sounds like you loaded the mag with the slide closed. If a mag is full, you should insert the mag with the slide locked open. Otherwise you are putting more pressure on the follower than it was designed for
4. Any chance you rode the slide down? Anything touching that slide will slow it down and not allow it to chamber that first round (or any round)
As far as shipping a gun to Ruger fir repair, the times I have had to do it it went like this:
Ruger emails me a shipping label
I drop the gun off
It comes back to my house unless the gun is replaced
If the gun is replaced, Ruger ships it to an FFL
I pay the FFL fee
I send the receipt for that fee to Ruger and they refund me the money for the fee
2. Yes but then I tried it with just a few rounds in mag and no it was not difficult to load last round
3. I did not try yet with the slide locked but I will. This is at least the 3rd time I've heard this and I did see on page 21 of the owners manual were it says this.
4. Not sure what you mean here
