both will accomplish what you need. the Gold dots are more reliable about expansion but they wont feed in all guns because of the mouth opening being so big. the Hydrashock will feed more reliable but they dont expand as big as the Gold dots. i would feel more than comfortable with either
Both are good to go. I use the Hydra Shock in my Baby Desert Eagle .45 and the Speer Gold Dot in my Desert Eagle .50AE. The .45 is EDC and the .50AE is for home defense. One thing for sure about the Hydra Shock is; it is time tested and proven.
FWIW, Gold Dots are what we have been carrying for years on-duty. Time tested and proven in real-world deadly force encounters across the country. They feed without issue in the Glock 30 and 21. I also carry them in my personally owned .45/.40/9mm/.380 weapons for consistency.
All of the municipal, state and county LE department that I've been in contact over the past years have moved to Gold Dots, and Speer is constantly in touch with our armorers and training department wrt new improvements they are working on in the Gold Dot series.
Hydroshock's are an old design and there are a lot of better options out there currently. I would certainly take Gold Dot's over them any day. Good quality bonded ammo is even better yet. Federal HST's and Ranger T bonded are some of the best. You can find the Civi version of the Ranger T bonded in places like Walmart or Academy it's just more expensive and labeled as Winchester PDX Bonded.
