I still use my WE Deagle from time to time and it is a beast. You can grab a kydex holster or cheaper amomax one pretty easily as well, only practical issues are extra mags are expensive and you'll need one of the looser pistol mag pouch designs for them.
Full metal, the recoil is satisfying and never fails to put a smile on peoples faces when I offer my Deeg to them to pop off a few shots after I see them eyeing it up, and perhaps someone here was misinformed when talking about gas capacity; it rocks. The Deagle is the only gas pistol I happily run in colder times of year even though the full metal slide is huge; I think its because of the gas reservoir and the very large nozzle used in the design.
The range is also pretty nutty, granted, mine has an autobot, stalker hop nub and crazy jet inner, but I reckon you'd still get impressive performance out of just an upgraded bucking. Lots of times people will be calling for a sniper to come over as there's a bloke in the distance pissing about and I just stroll up, do the classic one handed Hans Landa exaggerated aim, and proceed to miss completely hit every shot like the highly competent marksman I am. Because the barrel is fixed to the frame and doesn't move when the slide reciprocates, the accuracy is also really very good.
If you've got small arms or a small frame in general maybe it would be a bit of a pain but honestly its not really that heavy. Most of the metal isn't steel or anything so its not as ridiculous as the real deal and absolutely skirmishable for me at least. If you do get one, just make sure you clean and oil it after every skirmish and check nothings shaking itself loose like with most hard kicking airsoft guns.
Now, I know it sounds like I've been describing the second coming of Christ our lord and saviour in airsoft pistol form. It always seems a bit dodgy when someone sings the praises of any product too hard, but honestly? My Deagle has been amazing and never fails to perform, all whilst putting a huge grin on whoever I let try it out. So I recommend it whole heartedly in the hope that you pick one up and are as pleased with it as I've been with mine.
