So if I understand correctly, you want to sell off your current two pistols and have one gun to do both nightstand duty and carry?

If so, what is the total budget?  Can I assume well over a grand if you are considering the Legion?

You mentioned the 1911.  Can I assume you are comfortable carrying a full size pistol?

Depending on your budget, need for accessories, and size restrictions you might consider the following:

CZ:  https://cz-usa.com/product-category/handguns/  I have a surplus CZ-75B that I did some work and refinishing on.  If this sample is any indication of how they are made today, then get one because they are tanks.  They don't come with a rail, but the SP-01 version does.  There is a compact version called the P-01 that also has a light rail.  (I don't have experience with the latter two, but I hear good things.)

If a striker fired pistol is more to your liking, I have a P10C that I really like.  It fits my hand pretty well and has a very nice trigger for a striker gun.

CANIK:  http://www.canikusa.com/  I own three: the TP9SA, TP9SF, and TP9SF Elite.  I am thoroughly impressed with what I got for my money.  Good build quality, good triggers, good reliability.  I couldn't complain.  I can't speak from personal experience with the next two, but if you want an upgrade from the three I have, there is the TP9 Elite Combat or TP9 Elite Combat Executive.  They are more expensive to be sure, but might be more to your taste.

Archon:  https://archonfirearms.us/  I have been carrying the Type B for a while now and am loving it.  There were some teething issue to start, but after they were worked out, I've had no problems with it at all.  It's a pricey pistol, but if the Legion is in your budget, then so is the Archon.

Any of these pistols will have Youtube reviews galore.  Gunwatcher  https://gunwatcher.com/  might help you locate what you decide on.

Good luck and good shooting!

I have no problems with the 1911 platform as either a carry gun or a nightstand gun but the ones with rails can get pricey and honestly(?), I don't think the practice with the Ruger 22/45 will carry over very well to a center fire 1911.  At least it didn't for me.    I considered  buying a .22 LR conversion for my 1911(s) but they are expensive and prone to being finicky about ammo so I abandoned the idea.

If you are thinking of a 1911 pattern pistol with an eye toward common platform translating to carryover you might want to look more closely at the RIA lineup as they have a dual barrel/magazine pistol in .22/.45 ACP called the XT series.  Their 9mm combo gun pairs with their proprietary .22 TCM round but I don't think anybody actually makes a drop in .22 LR kit for the 1911 that doesn't cost an arm and a leg.

SIG makes .22 LR conversion kits for some of the P series pistol but not for the 1911 line up AFAIK.  One of those would still be under the $1000  for the base pistol plus the conversion - or they would last time I checked.    Glock just came out with the model 44 which is a .22 LR clone for the 9mm model 19 and if it is priced at or below the cost of the model 19 that should also get you in under the $1000 mark for both guns. 

I know this line of thinking kind of leaves the Ruger as the odd gun out but unless you are able to translate the experience of shooting the 22/45 a lot better than I was you may not find quite what you are looking for.
